DENTAL COTTON-HOLDER.

Specification of Letters Patent.

Application filed September 5, 1913.

Patented Nov. 11, 1913.

Serial No. 788,207.

T0 all whom it may concern:

Be it known that I, SAMUEL L. IHIT- RIGHT, a citizen of the United States, and a resident of lVaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Dental Cotton-Holders, which improvements are fully set forth in the following specication.

This invention rela-tes to improvements in devices of that class available for the accessible storage of a supply of absorbent, medicated, or other cotton, such devices being more particularly intended for dentists use, and being appropriately designated dental-cotton holders.

The object of this invention is to provide a dental-cotton holder which shall be simple and comparatively inexpensive as regards its construction; durable, eiicient and reliable in practical service; which sha-ll embody novel features of construction whereby are markedly facilitated both the operation of gaining access to the interior of the holder, proper, as for the charging thereof, from time to time, with fresh supplies of cotton, and the adjusting thereto and displacement therefrom, also as occasion may make needful, of the waste-cotton re ceptacle thereof; and which shall possess certain well-dencd advantages over prior analogous structures.

The invention consists in the combinations, details and parts whereby, together with the novel disposition and relative arrangement of said parts, the attainment of the foregoing object is rendered practicable, all of which will be hereinafter more specifically referred to and set forth in the appended claims.

In the accompanyin drawing, wherein the invention is Cleary illustrated, and similar reference-characters denote like parts throughout the respective views,-Fig ure 1 is a plan view of a dental-cotton holder embodying my said improvements, a fragment of the perforated mantle thereof being broken away. Fig. 2 is a side elevation of same, the waste-receptacle saddle thereof being shown in central, vertical section, as along the broken line a" :c of Fig. l, the perforated mantle and interior dome of the holder, being each partially broken away. Fig. 3 is a view showing in perspective and detached the saddle aforenamed in conjunction with the frictional keeper which I purpose making use of.

Having reference to the accompanying drawing, 2 denotes the interior dome of the device, provided with a base-plate 2, said dome having an openix 2 at its top. Within the dome 2 there 1s disposed a frictional keeper, the same consisting, in this instance, of a fiat bottom-member 3, merged at its opposite end-portions into upstanding, somewhat upwardly converging, opposite legs 3, 3, each having a terminal at its upper extremity turned oppositely to the opposite leg, and said keeper being positioned so that the space between its le 3, 3 registers vertically with the opening 2 thereover.

4 denotes a dome-like mantle, which overhangs and generally houses the dome 2, said mantle and said dome being so at variance in cross-sectional contour as to provide between them a chamber 4c', for the reception from time to time, and storage of supplies of fresh cotton, and said chamber being coextensive circumferentially with the holder, proper. The dome 2 is provided, by preference, with a circumferential ledge 4, at the lower portion thereof, and on which ledge rests the mantle 4f, when in position for service. Said mantle is provided with a plurality of perforations 5, preferably arranged in series circumferentially thereof, and the purpose of said perforations will be hereinafter explained.

The mantle l is surmounted by a saddle 5 for the reception and seating of a wastecotton receptacle 5". It is contemplated and preferred that the saddle aforenamed shall be capable of not only affording a seat for the receptacle 5, but of exerting a frictional holdingl force thereon, when the lat-- ter is in position for service; and to this end saddle 5 is provided marginally with a plurality of upstanding clip-members 6, each adapted to elastically impinge, at its upper portion, against the adjacent wall of the receptacle 5, the latter being inserted downwardly endwise between such clipmembers.

Any appropriate fastening medium may be availed of for securing the saddle 5 on the mantle 4:, though, as here shown, I have provided a central tie-stem 6, having a head 6, which tie-stem extends downwardly through the saddle 5, by way of a suitable fio opening' 7 V'formed centrally therein, thence downwardly through the dome 2, by way of the opening 2 formed therein at its top, and terminates at a point suitably distant downwardly from the top of the dome 2 to permit the same to crowd, end-on, between the legs 3, 37, of the keeper aforenamed, whereby a frictional holding force is exerted thereon by the latter. Also, in this instance,

the shank of said tie-stem is suitably threaded to receive la fastening nut 7 the central portion of the saddle 5 and of the crown of the mantle 4 lying, one upon theother, between the head 6 of said tie-stem, and the fastening nut afo'renamed, said saddle and said mantle being, accordingly, duly locked together, upon said fastening nut being adequately turned homeward, all as will be ite'a'dily understood.

' As to the practical operation ofy my improved cot-ton holder, it will be understood that'm'antle'e 'may be 'displaced from, and replaced on, the dome 2, by exerting lengt-hwise' on the stem 6^ a mere pulling force, in the former instance, andy a mere pushing force in thev latter instance, these opposite forces being readily applied to said stem, although indirectly in this instance, .by grasping the dome 2, withone'hand as at its lcircurriferential ledge 4f', and grasping, say, the saddle 5 with the lother hand. Again, when mantle 4 is displaced from the dome 2, a suitable supply of fresh cotton may be lodged upon the latter, the mantle 4 being then replaced upon said dome; whereupon the cotton will occupy the chamber 4', intermediate of, and formed by, said mantle 'sind said dome, respectively, access to said cotton, in comparatively small quantities, as required for service, being then had by way of any of the perforations 5. The discardment of the cotton, in said comparatively v small quantities, and after being soiled in use, the user effects by inserting the same ititothe receptacle 5, by way of the cus-V tomary cross-slitted top thereof, this receptacle being commonly formed from paper.

The positioning of the receptacle 5 on the saddle 5', and its removal therefrom, are effected in substantially the same manner as are effected the positioning of the mantle 4 on, and its removal from, the dome 2, as hereinb'efore explained.

The general parts of my improved cot-ton holder, aside from the receptacle 5, may be tional holding force on the recept-acle, Y

and various xminor detailsxof'the general construction, wit-hout departing from the scope of the claims hereto appended.

I claim: l v Y l 1. A dental-cotton-'hlder comprising an interior dome; a perforated 'mantle :overhanging and substantially "housing said dome; and means lwhereby, said mantle and said ldome tarefriction'ally vheld together.

2. A"'dentalic"otton holder comprising an interior dome; 'a perforated ,mantle overhanging "'and'sibstant-ially housing said dome, and having a "stem freely depending therein; and a keeper,f the "latter situated withinsaid dome, and adapted'toengage and frictiohally V'exert la holding forceon said stem.

3. Av'dental-c'otton liolder'compr'ising an interior `do'me; 4a perforated 'mantle overhangiiig Aand substantially housing "said dome, said'mjaiit-le surmounted by a Kwastereceptac'le saddle, having l'a stein tying said saddle thereto, and freely -d'e'per'iding within the'd'oine 'af'oretiamedgV and a keeper', the latter situated within -said domeand adapted to enga-'ge and frictionallyexert a holding force on'said stem.

4. A dental-'cotton holder comprising fah interior dome; a perforated mantle overhanging and substantially housing lsaid dome, said. mantle surmounted za wastereceptacle saddle affording a plurality ofiipstanding clip-members, and having a stem tying said saddle thereto, and freely depending within the dome aforenamed; and a' keeper, the latter situated withinsaid dome and adapted to engage and frictionally exA ert a holding force on said stem.
